CORK-SHELL-CUTTING MACHINE.

Patented Dec. 24, 1912. 1911. Serial No. 627,519.

To all whom 1' It may concern:

Be it known that I, ALEXANDER Boominrrr, a subject of the King of Hungary, and reeldent of the city of New York,'in the county of Kings and State of New York, have in vented certain new and useful Improvements in Cork-Shell'Cutting Machines, of which the following is a specification.

The present invention relates to an JIIlproved apparatus for cutting cork shells, or, as they are sometimes. termed hollow corks. This kind of work has been performed heretofore upon two separate machines by two separate operations. First the corks were cut or blocked out from cork strips, and, second, the corks were placed upon another machine for the purpose of cutting out the core therefrom to produce a cork shell-or hollow cork. Another Way, as far as known, to make cork shells is to .combi-ne the two machines heretofore mentioned upon one base, and to operate the cutters thereof by foot power, feeding the cork strips thereto byhand. While by means of this arrangement much time is saved, the operation of the device depends too much upon the skill of the operator.

It is now one of the objects of the present invention to construct an improved apparatus for cuttin cork shells, by means of which the wor is accomplished automaticall y at one settingl of the cork strips and by one operation of t e machine.

Another object of the invention is to provide an automatic feeding means for the strips to the cutters in combination with means which hold the said strips in position (luring the cutting operation.

A further ,object of the invention is to make the feedinggand holding devices adjustable to conform to the size of the strips at hand, and to the size of the desired.

A still further object of the invention is to combine the cutters and strippers of the machine in such a manner that all of the same may be rotated by one belt or its equivalent, and a rec-iprccatory motion imparted to the same by another belt or other means.

With these and other objects in view, which will appear asthe nature of the invention is better understood, the same consists in the combination, arrangement and cost-motion of parts hereinafter fully desc ifiied, pointed out in the appended claims cork shells and illustrated in the accompanying drawings it being understood that 'many changes may be made in the size and proportion of J the several parts and minor details of construction without de arting from the s irit I or sacrificing any 0 the advantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accompany drawings, in which I igure 1 is a front elevation, partly in, section, of a cork shell cutting machine constructcd in accordance with the present invention; Fig. 2 is a side elevation thereof; Fig. 3 is a vertical longitudinal section of the cor.:bined cutters and strippers Figs. I 4, 5 and 6 are sections taken on. lines 4-4,

5---5 and 6-6, respectively, of Fig. 3; Fig. 7 is a side elevation of the feeding and holding means of the machine; Fig. 8 is a front elevation of the device shown in Fig. 7; Fig. 8 is a plan view of the device shown in Fig. 7, and Fig. 9 is-a plan view of a detail of construction.

In the drawings, the numeral 20 designates the supportlng frame of the which is, preferably, U-shaped in cross section, as clearly shown in Figs. 2 and 7 of the drawings, and provided in its horizontal portion with a groove 21 and a slot 21, for a purpose hereinafter to be described. The supporting frame rests on legs or standards 22, 22, carrying bearings 22', in which the main drivingshaft 23 of the machine is journaled. Rotation may be imparted to this shaft in any suitable manner, for instance by keying ..o the same a pulley 24. which is driven by means of a belt or otherwise. The frame Qttsupports bearings 25 and 26 of any suitable -onstruction, in which are rotatably and reciprocatably arranged the cutting and stripping means of the machine. These cutting and stripping means are shown in dotail in l igs. 3 to 6, inclusive, and comprise a tubular arbor 2T, journalcd in the boar- I I a n s lugs 20 to 26, and provided in its front portion with a tapering portion 28, into which fits the conical end 2!) of a tuhular cork cuttor 30. united by forcing the conical portion 29 of I the cutter into the tapering portion 28 of the J arbor. in the arbor 27 is slidably arranged I a tubular mrmber 31, the outer diameter of which is considerably smaller than the inner i diameter of the a1'bo1'27. This tubular machine,

The arbor and the cork cutter arc member is provided with annular enlargements 32, 32, which will hold the same in concentric position relative to the arbor 27. The tubular member 31 has also a tapering inner end 32, into which fits the conical outer end 33 of a second tubular cork cutter 34. The cutter 30 serves to cut the exterior of the cork shell from the cork strip, while the cutter 34 cuts out the core from the shell. The tubular member 31 has in diametrically opposite portions longitudinal slots 35, 35, the walls of'which are engaged by a pin 36, which is secured to the arbor 27, whereby the said tubular member will rotate with said arbor, while its reciprocating movement is independent from that of said arbor. A stripper 37, for the core of the cork shell, is located within the cutter 3st, and attached by means of the pin 36 to the arbor 27. For removing the finished product from the cutters, a tubular stripper 38 is arranged between the cutters 30 and 84, its inner end being provided with outwardly extending projec tions 3t), 3 to which a ringAO is attached, which latter, in cooperation with the stops t1 and 42, upon the extension 43 of the bearing 26, limits the alternating; movement of the stripper 38. The projections 39 engage longitudinal slots 27 in the arbor 27.

From the foregoing it will be observed that the cutters and strippers are made to rotate together in their bearings, but that the cutters 3t) and 3-1 move back and forth in the same indepemlently of'each other, while the stripper 3? moves with the cutter 30, to which it is attached. The stripper 38, however, alternates by friction independently of said cutters and the stripper 37.

The cutters 30 and 8t, and so also the stripper 38 can be easily replaced by others, if shells of another size are to be made.

The bearings 35 and 26 receive lubricating material from the grease cups 44, 4.4, while the contacting surfaces of the cutters and strippers are lulnicated by providing holes 45, L5 in the stripper 38, in which holes are arranged, for instance, felt pieces 46, which are charged with lubricating material when the stripper 58 travels outside of the cutter :50. For this purpose a felt piece which had been soaked in oil, or other means may be supported by the frame of the machine in contact with the cutters.

Rotary motion is imparted to the cutting and strippinginechanisn'i, for instance, by means of a belt 4.? running over a pulley 48, which is keyed or otherwisa attached to the arbor 27, and over a pulley t9, mounted upon the driving shaft 23. It will be observed tliat, sincc the pulley 48 travels with the arbor 27, the heightof the cylindrical surface. 49' of the pulley 4-2) must be at least as much as the width of the belt-47 plus the amountof reeiprocatory movement in one direction of the arbor 27.

Aback and forth movement is imparted to the cutting and stripping mechanism from a rotary shaft 50, which is journaled in extensions 51, 51 of the supporting frame of the machine. Upon this shaft is mou-nt-' ed a-loose pulley 52 and a keyed pulley 53, for the well known purpose. Two eccentrics 54 and 55 are keyed to the shaft 50; the disk of the eccentric 54 being set 90 in angular relation behind the disk of the eccentric The straps 56 and 57 of these eccentrics are rigidly attached to bars 58 and 59, respectively, which in turn are pivoted at 60 and 61, respectively, to arms 62 and 63,,which latter are secured to rods 61 and 65, respectively. The rods 6st and 65 are slidably mounted one below the other in the end walls 66 and 67 of the U-shaped supporting frame of the machine. To the outer ends of the rods 64 and 65 are attached arms (58 and 69, respectively, the other ends of which engage the arbor 27 and the tubular member 31, respectively, in such a manner that the said arbor and tubular member are free to turn in said arms but are caused to move.

back and forth with the same.

zontally extending transverse plate member '71, provided with a perforation 72 .in their longitudmal axis of the arbor 27. 'From j this plate member projects downwardly near its middle portion a bracket 73, having a slot Tat extending throughout its length, and being shiftably arranged upon the supporting frame 20 of the machine. The support 70 is provided with a ridge T5, seated in the groove 21 hereinbefore described. A set screw 76 holds the bracket 73 and thus the plate member 71 in the desired position upon the supporting frame; vertical horizontally extending transverse plate member 7'? are secured pinsTS, which project through holes 7 9 'in the plate member 71, and are held in engagementtherewith by means of set screws 80. 'The plate members 71 and 77 are.thus held in parallel relation to each other, and may be set to a distance which corresponds substantially' to the thickness of the cork strip St to be worked upon. This cork strip rests upon a. base plate 82, which is attached to a lug 83, having a slot 84, engaged by a screw 85, the threads of-which mesh with the interior threads of ahole in the plate member Ti. By means of this arrangement, the base plate 82 can be raised onlowered as the cork strips vary in their heights.

The cork strips are fed to the cutters by To a second lltl the following device: A bar 86 is slidably the fingers to he raised I 80. This lever is ar ai'iged slots 5 Ht which are engaged hy screws 00. .10 to clamp the hloirlcs against the hires ot' the plate lllt'litliil' Tl. Obviously by means of this arrangement the har St) and the ele' inents attached thereto may he raised or lowered relative to the supporting 'l'raine To. To the har of; are pivoted at 01, .11 :i pluiality ot' 't'ci'ding lingers 0;. 0;, having arc shaped slots J 1, rat-h ot which is in engagement with the pivot 01 ot' the adjoining feeding t'inger 0:3 upon said har. Springs 05. 075, engaging lugs 00 upon said.ha and the hook shaped ends 07 ot the feeding lingers 02, tend to force said lingers against; the upper face Ot the cork strips $1. The slots 03 serve to allow the pointed ends of or lowered to ditterent horizimtal planes, so that the same will always engage the upper surface of the cork strip, no matter how uneven the latter be.

When the feeding bar is moved toward the plane of the pulley 523, the feeding tingers 02, which are, by means of their springs 95, held in engagement with the cork strips tilt! a pawl with the teeth of a ratchet wheel, will more the said cork strips toward the cutters and strippers. The means for doing this comprises a lever 05, which is provided at its upper end with a slot 00, engaged by a pin 100, which latter is attached to the bar in the recess 10.1 of a disk 102, which is rotatahl held upon a spindle 1025 engaging the slot 74 in the bracket 73, and kept in position thereon by means of a nut 104, meshing with the screw threads of said spindle. The lever 05 is kept in the recess lhl hy a disk 101, at taehed in any suitable inanntr to the disk 102. In shifting the spindle 103 in the reeess 74, the fulcrum of the lever 98 may he 'aried and thereby the stroke of theat'eeding bar 80. To the lower end 01 .the lever 08 is pivoted at 105 a 'hellcrank lever 100, which is lulerinneitl at 107 to an extension 105: of the bracket 73. The free end of the hell-' crank lever 106 carries thereon a roller 100', which is arranged in the clamp 110 to the rod (31. Springs 111 and are attached at one oi their ends to the lever 08 and at their other ends to the extension 108 and one of the spindles 7s, respectively, and tend to bring the lever 08 back into its normal position shown in l ig. 7 of the drawings. it will he ohserved from the foregoing that, when the nose 100 acts upon the roller 1.00 and depresses thus the substantially horizontal arin ot the hellcrank lever 106, the upper end of the lever 08 will he moved toward the rear of the machine, whereh the leeding lingers will move the cork trip a jiredeterinini-tl distance toward the plane of the pulley 53, which distance depends upon the stroke of the lever 08.

'lhe nii'ans tor holding the cork strip in position during the cutting operation of the rotary iriii'ti-rs comprises a prrsscr tool 110 in the form ol' :1 hell 'rank lever, which is 'l'iileriiinrd at 117 to tlit' plate uieinhcr T7, and provided at its suhstantiall verti al arm with a ring-shaped clamping jaw 118, the inner face of which is provided with a plurality ot' teeth This ring ll2lj)t.tl jaw is arranged roni-entrirally with the arhor 27 in an opening 11!) in the plate inninhcr TT. and is normally held out oi" contact. with the ork strip hr in tans ol' a spring 1520. lo the horizontal ai'in ol' tllt helli- 'ank lever 11; is pivoted at 121 a tug 122, which arries at its l'reiend a roller 1'3 projecting through the slot :31 toward the rod (i-i. 'lhe horizontal arin ol the hellcrank lever .110 is slotted at 121. This slot is engaged h a screw 2-7, passing through the lug 121, to clamp said liig and hellcranh lev r 110 to gether, or to allow the lug 12; to rise without a tl'ectiiig the position of the hclh-ranii it ver 110. when the screw 1-35 is loosen: l. .\lotion imparted to the hclli-rank lt'K't'l' 11p h a sleeve 120, which is [ixcdly atta hed to the rod 0:3. As this sleeve moves toward the roller 3, it will lil't thesanic and. when the lug 1:22 is rigidly connected h v means of tinscrew 125 with the hclli-rank le'vi-r Hit, it will press the jaw 118 agaiiot. the cork strip 41. and hold the same against inoi'ion long as the roller 12 3 is kept in i-nuageineiil with the sleeve 120. When disengaged thercl'roin, the spring .120 will l'ii-re the jaw 118 into its inoperative position (shown iii Fig. 8 ol' the drawings). 11' it is desired to operate the machine without holding the cork strip 81 against movement, the screw" 125 is loosened, wlii-rehy the lug 122 will he allowed to rise without torringtlie jaw 118 against the cork strip H1.

since the disk ot the eccentric 54 is 00 oehind the disk of the ecoentricfifi, the sleeve will lift the roller 123 hct'ore the rotary cutters start their operations, or in other words the jaw '1 18 will hold the cork strip against niovcineiit hy the time the rotarv cutters reach the cork strip 81. As

lof is disengaged in order to the eccentrics are rotated, first the rotary cutter 3 will perform its cutting operation,

and then start its reciprocating movement backward, while the cutter 3O Wlll stlll continue its reciprocatmg movement forward.

Beforeit, however, will commence the cutting, the stripper 37 will push the core of the shell through the opening 72 in the plate member 71 into the chute 127, wherefrom it will fall, owing to the inclination of said chute, into a receptacle below the same. The cutter 3O enters then the cork strip, performs its cut-ting operation since the arbor 27 is still advanced. This arbor, in its rotation and forward movement, will carry with it by friction the stripper 38 until it is stopped in its advance movement by the stop 41 upon the extension 43 of the hear ing 26. The cutting operation being performed, the shell will remain within the rotary cutter 30, which will then start its outward movement carrying with it the stripper 38 until it abuts against the stop 42 of the extension43. cutter 30 continues its outward movement, the shell is pilghed by the stripper 88 into the chute 12$3it0 slide down into a receptacle below thesame. Thesleeve 126 is arranged at suchalilace upon the rod that it will hold the jaw 1-18 in engagement with the cork strip until after the cutter 30 has been withdrawn from said strip. As soon as the cutter 30 has been withdrawn the nose 109 is broughtiuto engagementwith the roller 106 to feed the cork strips into position for the next cutting operation. The cycle of operation now described is then. repeated.

What I claim is:
